The season of Advent focuses on the coming of our Lord Jesus Christ, and this first Sunday establishes this theme for the rest of the season. The Son of God came long ago to be our Savior, “a righteous Branch” descended from David (Jer. 33:15). As He then came into Jerusalem, riding on a lowly donkey to sacrifice Himself for the sins of the world (Luke 19:28–40), so does He come to His Church today in the humility of Word and Sacrament to deliver the fruits of His Passion: the forgiveness of sins and eternal life. He absolves us and establishes our hearts “blameless in holiness before our God and Father” (1 Thess. 3:13). The same Lord Jesus, who came to Jerusalem then and who comes to us now in peace, will come again with power and great glory on the Last Day.
